29. A 60-kg girl weighs herself by standing on a scale in
an elevator. What does the scale read when (a) the eleva-
tor is descending at a constant rate of 10 m/s, (b) the ele-
vator is accelerating downward at 2 m/s², and (c) the ele-
vator is ascending at 10 m/s but its speed is decreasing by
2 m/s in each second?

5. Apart from the gravitational force, a 1.0 kg particle is subject to two external forces that vary with the particle's height the following: F = (10 – h) j, F, 1 j. Both F, and (h + 1)2 F, are measured in newtons. The particle starts from rest at h = 0. Use g = gravitational acceleration. (a) particle will begin to move. 10 m/s? for the Draw the free-body diagram of the particle at h = 0 to explain in which direction the What is the particle's speed at h = 1.0 m?

You hang a 1.0 kg mass from a spring scale. But this time, instead of holding your hand still so that the acceleration is zero, you let your arm drop so that the mass accelerates downward at 5.2 m/s2. What force (how many Newtons) will the spring scale read while this acceleration is happening assuming that you are standing on the surface of Earth, so that the force on the 1.0 kg mass due to gravity is 9.8 Newtons?
